This is a 650mah battery for your Done Smoking electronic cigarette. This is the battery offered in line with the Done Smoking battery that forms part of our standard starter kits.
As with everything in life, you have to start somewhere! This is the battery we recommend that a novice or "new starter" begin with. It has a lower fixed voltage and will allow you to begin your electronic cigarette experience gradually, moving on to other battery units in time when (and if!) you feel ready. This is a good ground level, everyday battery unit.
